  1. A coat originally costs $120 and is on sale for 25% off. What is the sale price?

    Answer: $90

    25% of $120 = $30 discount, so sale price = $120 − $30 = $90.

  2. What is the value of the expression 2³ + 4² − √25?

    Answer: 19

    2³ = 8, 4² = 16, √25 = 5; so 8 + 16 − 5 = 19.

  3. A worker earns $15 per hour and works 38 hours in a week. How much does she earn that week?

    Answer: $570

    15 × 38 = $570.

  4. A rectangle has a length of 14 cm and a width of 5 cm. What is its perimeter?

    Answer: 38 cm

    Perimeter = 2(14 + 5) = 2 × 19 = 38 cm.

    Answer: 0.375

    3 ÷ 8 = 0.375.

  6. A class of 30 students has a ratio of boys to girls of 2:3. How many girls are in the class?
